Monitoring system for detecting degradation of a propulsion subsystem

a propulsion subsystem and monitoring system technology, applied in the direction of process and machine control, instruments, navigation instruments, etc., can solve the problems of failure inability to accurately predict the life cycle of the components of the propulsion subsystem, and conservative or fixed time schedules, so as to reduce the fuel consumed and/or emissions, and less wear or use of the component

AI Technical Summary

Benefits of technology

The system enables real-time tracking of component life, reduces unplanned maintenance, minimizes service interruptions, and extends the useful life of propulsion subsystem components, thereby lowering lifecycle costs and improving operational efficiency.

Problems solved by technology

Operation of the propulsion subsystem over time can degrade components of the propulsion subsystem, which may lead to failure of the propulsion subsystem.
These types of maintenance schedules, however, use conservative or fixed time schedules.
Based on the set of assumptions, the conventional maintenance schedule may not be based on the usage and / or operation of the vehicle system, and can incorrectly predict a shortened life cycle of the components of the propulsion subsystem.
This conventional maintenance schedule can thereby increase costs of inspections for components that are not at end of life and / or do not require replacement.
Additionally, due to the frequent inspections, the vehicle systems may be taken out of service when inspections are not needed.
This can decrease the efficiency at which a transportation network of vehicle systems operate.
Additionally, during inspection of the components, contamination of components and / or damage to components may occur, thereby decreasing the efficiencies of the vehicle systems.
On the other hand, significant usage of the components and / or systems can result in the components degrading faster than expected.
This can result in the components becoming irreparably damaged prior to the next scheduled inspection.

Embodiment Construction

[0018]Various embodiments described herein relate to detecting degradation of a vehicle propulsion subsystem. The degradation may be detected by a monitoring system that is configured to analyze a propulsion subsystem of a vehicle system. The vehicle system may include a single or plural propulsion-generating vehicles. Each of the propulsion-generating vehicles may include a propulsion subsystem. The propulsion subsystem may include components such as one or more engines, motors, alternators, generators, brakes, batteries, turbines, turbochargers, oil filters (e.g., centrifuge filters), and / or the like, that operate to propel the vehicle system. The vehicle system can include one or more locomotives or other rail vehicles, automobiles, marine vessels, mining vehicles or other off-highway vehicles (e.g., vehicles that are not designed for travel on public roadways and / or that are not legally permitted for travel on public roadways), airplanes, or the like.

Abstract

A system detects a parameter and generates a first trip plan to automatically control the vehicle according to a first trip plan. A controller is connected to a sensor and configured to receive the parameter. The controller is configured to generate a new trip plan or modify the first trip plan into a modified trip plan based on at least one of a cumulative damage or an end of life. A new trip plan or the modified trip plan is configured, during operation of the vehicle according to the new trip plan or the modified trip plan, for at least one of an adjustment in velocity or avoiding one or more operating conditions of the vehicle, relative to the first trip plan.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Application No. 62 / 491,765, filed 28 Apr. 2017, the entire disclosure of which is incorporated herein by reference in its entirety.FIELD[0002]Embodiments of the subject matter disclosed herein relate to detecting and / or predicting the degradation of a vehicle propulsion subsystem.BACKGROUND[0003]Various vehicle systems include a propulsion subsystem. The propulsion subsystem may include engines, motors, pumps, turbochargers, oil filters, alternators, radiators, and / or other devices or machines that operate to propel the vehicle system. Operation of the propulsion subsystem over time can degrade components of the propulsion subsystem, which may lead to failure of the propulsion subsystem. The propulsion subsystem can be inspected to identify and / or repair damaged components based on a conventional or fixed maintenance schedule.[0004]These types of maintenance schedules, however, use cons...
